This commit fixes a request handling bug introduced in #6868, which caused OPA to treat all incoming chunked requests as if they had zero-length request bodies. The fix detects cases where the request body size is unknown in the DecodingLimits handler, and propagates a request context key down to the `util.ReadMaybeCompressedBody` function, allowing it to correctly select between using the original `io.ReadAll` style for chunked requests, or the newer preallocated buffers approach (for requests of known size). This change has a small, but barely visible performance impact for large requests (<5% increase in GC pauses for a 1GB request JSON blob), and minimal, if any, effect on RPS under load.
